Hurry helpp I’m on a time limit!Which of the following is a true statement? CM=CD
2(MB) = AB
1/2 (AM) = AB

The true statement is 2(MB) = AB

Step-by-step explanation:

The given figure shows how to bisect a segment

∵ CD is the perpendicular bisector of AB

→ That means CD is perpendicular to AB and intersect it at its mid-point

∴ CD ⊥ AB

∵ CD intersects AB at point M

∴ Point M is the mid-point of AB

∵ M is the mid-point of AB

∴ AM = MB

→ That means each part is half AB

∴ AM = MB = AB

∵ MB = AB

→ Multiply both sides by 2

∴ 2(MB) = AB

∴ The true statement is 2(MB) = AB

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
